[HDFS-dev] [jira] Created: (HDFS-1669) Datanode servlets need information about the namenode to service the request

Federation: Datanode servlets need information about the namenode to service the request
----------------------------------------------------------------------------------------

Key: HDFS-1669
URL: https://issues.apache.org/jira/browse/HDFS-1669
Project: Hadoop HDFS
Issue Type: Sub-task
Components: data-node, name-node
Affects Versions: Federation Branch
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Fix For: Federation Branch

Attachments: HDFS-1669.patch


Prior to federation datanode had only one namenode. In servlets hosted on datanode, a DFSClient was created to the only namenode to serve the request. However with federation datanode has multiple namenodes. When a request is redirected to a datanode, it does not know which namenode to use for servicing the request.
This results in TestHftpFileSystem failure.
